Don't confuse the Disabled Player exception with the salary cap relief teams sometimes receive after losing a player to a career-ending injury or death (see question number 63). The Disabled Player exception allows a team to acquire a replacement player. The salary cap relief removes a contract from the team's books.

Oh, and Zillgitt in no way suggests that they get actual cap relief - he is just misusing the phrase. They get an exception to sign a player. Read the entire article and at no point does he suggest that George's salary actually comes off the books.
